Intro. the brand of Cain and the daughter of Lilith and Lucifer. Dean and Sam sought a way to kill Abaddon as Metatron deceived everyone. After Dean and Sam interrupted the process to lock demons in hell and Metatron had their victory making all angels fall from heaven, things came out of control. Dean had to lie to Sam and Gadriel entered Sam's body to heal him but in the end Gadriel ended up cheating on them entering the metatron team and they managed to get Sam to cast out the angel. Dean and Sam continued on the road looking for a way to kill Abaddon. Dean went on a way and had to join Crowley to get the first sword to kill the knight. Sam and Castiel tried to seek traces of Gadriel as Castiel tried to heal Sam. Dean got the brand of Cain but something changed in it.
